Abstract

The aim of this study is to produce optically
transparent nanofibers with adequate electrical conductivity for optoelectrical
applications where transparency and conductivity are needed. Therefore, conducting polyacrylonitrile/silver nitrate (PAN/AgNO₃)
nanofibers were produced by electrospinning with different deposition times ranging
from 1 minute to 10 minutes. The effect deposition time on the sheet resistance
and optical transparency of the nanofibers were investigated. The surface
characteristics, electrical properties and transmittance values of the
electrospun mats were evaluated. Nanofibers with diameters under 700 nm were
obtained. With the increasing deposition time, the sheet resistance and
transparency of the samples were decreased. In order to figure out the optimum
deposition time, figure of merit of the samples were calculated. Figure of
merit results showed that the sample deposited for three minutes had the best
performance among the others. It was seen that the results were comparable with
the literature and conducting PAN/AgNO₃ nanofibers are promising for
future applications.
